High frequency non-ionizing radiation, emitted by mobile phones, is often in the news. The effects of high frequency electromagnetic fields (HEFs) derived from mobile phones have been discussed since the 1950's. Neuroscientists from Bochum have studied this and for the first time, they provide proof that extremely high-powered electromagnetic fields (EMFs) indeed influence learning processes on the synaptic level within the brain, independent from other factors like stress. "For this effect, very high values are necessary. These do not occur during the daily use of mobile phones", explains Dr. Nora Prochnow (Medical Faculty of the RUB).
